Не могу использовать Rx Java с Hengam SDK

Question

Я недавно добавил Hengam SDK в мой проект; но, к сожалению, я больше не могу использовать Rx Java, и это приводит к дублированию исключений. Стоит отметить, что до добавления SDK в проект все работало правильно.

Вот трассировка стека:

Что с ним не так? Есть ли конфликт с SDK или ему нужна дополнительная конфигурация для использования Rx Java? Любой ответ будет оценен ...

Answer 1

AFAIK, Hengam имеет настроенный RxJava2 (для сохранения окончательного размера SDK ниже). Поэтому, если вы хотите использовать RxJava2 вместе с Hengam, вам нужно исключить его пользовательский RxJava2 и реализовать реальную библиотеку.

implementation ('io.hengam.lib:base:1.0.8')  {
   exclude group: 'io.hengam.lib', module: 'rxjava'
}

implementation 'io.reactivex.rxjava2:rxjava:2.2.9'

Так что io.hengam.lib:rxjava не будет импортирован в путь к классам, и вместо этого RxJava2 из ReactiveX будет добавлен.

Примечание :
1. Используйте RxJava2 версии 2.2.9 или выше.
2. RxJava3 имеет другую упаковку по сравнению с RxJava2. Поэтому убедитесь, что вы добавили RxJava2

Answer 2

Вам необходимо исключить группу Rx Java из зависимости или удалить зависимость Rx Java из gradle.

implementation ('io.hengam.lib:base:1.0.5')  {
    exclude group: 'io.reactivex.rxjava2', module: 'rxjava'
}
